A novel Ce3+:YAG doped sodium glass (CeYDG) with low-melting temperature of 693°C and high internal quantum yield of 68% for white-light-emitting diodes (WLEDs) is demonstrated. The glass phosphor possesses glass transition temperatures of 578°C which exhibits a better thermal stability to overcome the thermal limitation of conventional Ce3+:YAG doped silicone due to low thermal stability of around 150°C. To the best of authors’ knowledge, this is the highest quantum yield yet reported for… Expand
